Reply	Anonymous says: A lot of comments about why clockwise/anti-clockwise but no one has answered: are some runners favoured?. Some thoughts: 1. Sure, some runners have one leg longer or stronger, but does that actually equate to an advantage? 2. The curve is fairly gradual, so perhaps can it be regarded as straight locally anyway? 3. Having an asymmetric body may be a disadvantage on the straights compared to someone symmetric (poorer technique perhaps). 4. Finally, if there is an advantage, is it significant/material?  (no votes) Tags: unanswered, domestic science, human body.

Reply	Anonymous says: If the outter leg ran 10cm wider than the inner leg on the curves, it would run an extra 63cm in total (per lap). Interestingly, this is independent of the size of the circle being run around and is simply 10cm*pi*2=63cm. If the track was as big as a planet, the outer leg would still only have to travel an extra 63cm!Do runners run with one foot in front of the other, or slightly aside? I do not know, but running say an extra 63cm per lap with the weaker leg could be the difference between winning and losing.  (1 vote) average rating:1 Tags: unanswered, domestic science, human body.

If you run on the curved part of a 400m running track, the right leg is adducting more that the left.  I have no idea if this is related to the question of why we run anticlockwise, but it will surely favour some runners over others, viz those who regularly train on a track vs those who train by running on roads or crosscountry.  (no votes) Tags: unanswered, humanbody, domesticscience. posted on 2012-07-03 09:50:01 | Report abuse

Reply	Anonymous says: In occultism, going anticlockwise is associated with the left-hand path, i.e. with evil. If there is anything in that idea, all those millions of people looking at athletes going withershins around stadia are contiually replenishing the magic potential for evil.Even if this is nonsense, the people who set things up this way, may belive it works.  (no votes) Tags: unanswered, domestic science, human body.

Reply	Ray says: re the plane-turning comment... I was taught that small planes turn easier in one direction due to the airflow from the prop being somewhat spiral in nature, causing an asymmetrical drag/lift on one side. There is commonly a fixed trim tab on the tail to offset this. Then there is the precession of the motor/prop mass that rotates in one direction, but my physics isn#39;t up to analyzing the effect!  (no votes) Tags: unanswered, domestic science, human body.

Reply	Jasper10 says: Given the choice if I fell over, it somehow feels safer to fall to my left than to my right. I am right handed, as are most people in the World. So why might it feel safer? Well, when I fal left, the left hand may come into conact woith the ground before i have a chance to prepae myself for the fall, this causing my arm to bend beyond the point where it can offer shock absorption, However, being brought around my body, is not so vulnerable, allowing my right arm, which is stronger as more used, given that i am right handed, to remain effective, or at least more so than the left arm, at absorbing the impact from the fall and thus minimising injury to me. I wonder if the person who posed this question is left-handed?  (no votes) Tags: unanswered, humanbody, domesticscience.
